1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundAs part of its COVID-19 response, South Africa banned tobacco sales between March and August 2020. We examined self-reported tobacco use before, during and after the ban among a rural South African population with high HIV prevalence.

methodsBetween May 2021 and November 2022, we conducted a telephonic survey on tobacco use among a purposively selected subset of a population-based cohort in rural KwaZulu-Natal. We compared the prevalence and characteristics of people who retrospectively reported tobacco use (combustible, smokeless and/or electronic cigarettes) before, during and after the ban. Multiple logistic regression assessed predictors of tobacco use during and after the ban.

resultsOf 1448 people eligible, 752 (51.9%) completed the survey. Among 449 people who used tobacco before the ban, 118 (26.3%, 95% CI 22.2% to 30.4%) reported abstinence during the ban, of whom 103 (87.3%, 95% CI 81.3% to 93.3%) relapsed afterwards. Of the 39 people (8.7%, 95% CI 6.1% to 11.3%) abstinent after the ban, most had used tobacco during the ban and quit afterwards. People with HIV were more likely than people without HIV to stop during the ban (adjusted OR (aOR) 1.57, 95% CI 1.01 to 2.44, p=0.046). For each unit increase in daily combustible tobacco use before the ban, individuals were less likely to stop using tobacco during the ban (aOR 0.92, 95% CI 0.88 to 0.97, p<0.001).

conclusionsSouth Africa's 2020 tobacco sales ban, prompted by the COVID-19 pandemic, was associated with a 26% decrease in retrospectively reported tobacco use prevalence among a rural cohort. Tobacco use largely, but not completely, rebounded after the ban.
